CFC's 20th annual plant sale, and to celebrate, the organization aims to have 20,000 native plants in the ground from the sale. Buyers can choose from a huge selection of robust, hardy native plants, and knowledgeable volunteers will be on hand to answer questions. As part of CFC's Milkweed for Monarchs campaign to support monarch populations, at least five species of native milkweed plants will be available for $2.50 each.
